Download
Download a file from the web address specified in `HKCU\Software\Microsoft\OneDrive\UpdateOfficeConfig\UpdateRingSettingURLFromOC`. `ODSUUpdateXMLUrlFromOC` and `UpdateXMLUrlFromOC` must be equal to non-empty string values in that same registry key. `UpdateOfficeConfigTimestamp` is a UNIX epoch time which must be set to a large QWORD such as 99999999999 (in decimal) to indicate the URL cache is good. The downloaded file will be in `%localappdata%\OneDrive\StandaloneUpdater\PreSignInSettingsConfig.json`.
